Description

【発明の詳細な説明】 濃厚物質を搬送するための装置 本発明は、濃厚物質ポンプと、高圧搬送導管を介して濃厚物質ポンプの圧力接 続管に接続可能な濃厚物質配分器とを有する、濃厚物質、特にコンクリートを遠 くへ搬送するための装置に関する。 濃厚物質を遠くへ搬送するには、濃厚物質の粘性および高圧搬送導管の壁摩擦 に依存して狭い限界がある。到達可能な搬送距離を延ばすために、管壁と搬送管 内に生じ搬送管に沿うて送られる濃厚物質連続体の表面との間の範囲に滑り剤を 注入することにより壁摩擦を低減することは、既に提案されている(ヨーロッパ 特許第0633863号)。この方法は、特に搬送距離が数百メートルに達する 、固形物質の割合の高い濃厚物質の搬送の場合に適用可能である。液状コンクリ ートのような液体の割合の高い濃厚物質の場合、例えばトンネル建設のためには 、数千メートルの搬送距離が目標となるが、この距離は周知の滑り剤注入による のみでは達成することができない。 前述のことより、本発明の課題は、濃厚物質、特に液状コンクリートを遠くへ 搬送するための当初に述べた形式の装置を改良し、所与のポンプ出力における到 達可能な搬送長さを大きく高めることを可能にすることである。 前記の課題の解決のために、特許請求の範囲第1項に記載の構成要件の組合せ が提案される。本発明の有利な構成と形成が、従属請求の範囲に記載される。 本発明による解決は、特に次の技術思想に基づく。すなわち、搬送過程時に高 圧搬送導管の全長の1部のみが搬送すべき濃厚物質を付与され、これに対しその 都度の濃厚物質区間よりも長い残りの区間が低粘性でありかつ壁摩擦の小さい圧 力媒体を付与されることにより、高圧搬送導管 における圧力降下を低減することができるとの技術思想である。これを達成する ため、本発明は、高圧搬送導管がポンプ側および配分器側にて2つの接続部の間 で交互に切り替え可能なそれぞれ1つの管転轍器に接続されており、その際ポン プ側管転轍器が、その1つの接続部にて濃厚物質ポンプの圧力接続管と、そして 他の接続部にて入口側で貯槽を介して低粘性圧力媒体を付与可能な圧力媒体ポン プの圧力接続管と結合されており、また配分器側管転轍器が、その1つの接続部 にて濃厚物質配分器と、そして他の接続部にて戻し導管を介して圧力媒体ポンプ の貯槽と結合されており、さらに配分器側管転轍器が、到達する搬送材料流に生 ずる濃厚物質から圧力媒体へまたは圧力媒体から濃厚物質への材料交換に応じて 切替え可能となっていることを提案する。このため、搬送材料流における材料交 換に対応して配分器側管転轍器の切替え過程を作動させるセンサが設けられてい る。 搬送装置の定常運転では、ポンプ側管転轍器が配分器側管転轍器に依存して、 特にこれと同期して切り替え可能であることが有利である。この場合、搬送区間 に沿い常に同じ圧力媒体量および同じ濃厚物質量があることになり、濃厚物質の 安定性が与えられて圧力降下がほぼ一定になることが達成される。 分離位置における搬送すべき濃厚物質と圧力媒体との間の混合を防止し、かつ 材料交換の発生をセンサにより容易に検知できるようにするため、本発明の有利 な実施例では、モルヒ弁体(Molchschleuse)がポンプ側管転轍器の範囲にて高圧 搬送導管内に開口し、このモルヒ弁体を介して、ポンプ側管転轍器の切り替え毎 に、導管横断面に適合した少なくとも1つの分離体が高圧搬送導管内に挿入可能 であることを提案する。他方において、高圧搬送導管が配分器側管転轍器の範囲 に、または戻し導管が貯槽の範囲に、到達する分離体の取り出しのためのモルヒ 弁体またはモルヒ捕捉体(Molchfaenger)を有するようにすることができる。配分 器側管転轍器を常に適宜の時期に切り替え得るように、当該管転轍器 の近くに到達する分離体に応動して切替え過程を作動させるセンサを設けるのが 有利である。この場合、該センサは、例えば分離体が存在することに応動する磁 気センサまたは超音波センサとして構成される。 特に初期位相時および濃厚性の変化する濃厚物質を搬送する場合、濃厚物質ポ ンプの所定の搬送圧力または高圧搬送導管内の所定の圧力降下に応動して、ポン プ側管転轍器を切り替えるためのセンサを設けることが特に有利であることが判 明した。この手段により、搬送装置を所定の搬送出力でかつ常に最適の濃厚物質 搬送量で運転することが可能となる。運転障害を防止するためには、圧力媒体ポ ンプからポンプ側管転轍器に通ずる導管に逆流防止器を設けることが重要である 。 本発明による遠距離搬送装置は、トンネル建設に用いると有利である。この場 合、濃厚物質配分器をトンネル型枠配分器として構成することができる。 搬送されるべき濃厚物質が液状コンクリートである場合、水または低粘性ベン トナイト・水混合物または液体ポリマーが圧力媒体として用いられる。 以下に、本発明を図面に図式的に示す実施例により詳細に説明する。 図1は、トンネルコンクリート打ちのための液状コンクリート用搬送装置の図 式図である。 図2は、図1に対し転轍器を切替えた図1の装置の部分図である。 図に図式的に示す定置のポンプ装置は、トンネル11内にあるトンネル型枠配 分器10にコンクリートを搬送するためのものである。該ポンプ装置は、主に特 に2シリンダ・ピストンポンプとして構成された濃厚物質ポンプ12と、2シリ ンダ・ピストンポンプとして構成された圧力媒体ポンプ16と、定置配置の両ポ ンプ12、16とトンネル型枠配分器10との間に延びる約5000m長さの高 圧搬送導管20と、高圧搬送導管20のポンプ側および配分器側端部に接続され 、交互に2つの接続部の間を切り替え可能なそれぞれ1つの管転轍器22、24 とよりな る。前記濃厚物質ポンプ12には、大きな材料供給槽タンク14を介して液状コ ンクリートが供給され、また圧力媒体ポンプ16には、大きな貯槽18を介して 、例えばベントナイト・水混合物よりなる圧力媒体が供給される。この場合ポン プ側管転轍器22は、その1つの接続部26で導管28を介して濃厚物質ポンプ 12の圧力接続管30と結合され、これに対し管転轍器22の第二の接続部32 は、導管34を介して圧力媒体ポンプ16の圧力接続管36に接続されている。 導管34には、安全のため、圧力媒体ポンプ16から管転轍器22の方へ開放し 、そして反対方向に閉じている逆流防止器38が設けられている。 配分器側管転轍器24は、その1つの接続部40でコンクリート導管42を介 してトンネル型枠配分器10に接続され、これに対し同管転轍器は接続部44に てベントナイト・水混合物用の戻し導管45を介して貯槽18と接続されている 。図1に示す位置において、高圧搬送導管20は管転轍器22を介して圧力媒体 ポンプ16と、そして管転轍器24を介して貯槽18と連絡しており、これに対 し図2に示す位置では、高圧搬送導管20は管転轍器22を介して濃厚物質ポン プ12と、そして管転轍器24を介してトンネル型枠配分器10と接続している 。管転轍器22を適宜制御することにより、高圧搬送導管20にコンクリートと 圧力媒体とを交互に供給することが可能となる。図2に示す実施例では、約20 00m長さの導管部分46には液状コンクリートがあり、3000m長さの導管 部分48には圧力媒体がある。コンクリートと圧力媒体との間の分離位置には、 モルヒ(Molch)として構成された分離体50がある。このモルヒは、コン クリートと圧力媒体との混合を防止し、そして外部から配分器側管転轍器24の 切り替えのために検知し易いものである。この検知容易のために、分離体50は 磁気材料または磁化材料を備え、これを配分器側管転轍器24の近くに配置した 磁気センサ52により検知して切替信号の生成に用いることができる。 分離体50は、モルヒ弁体54を介し管転轍器22の切替過程毎に高 圧搬送導管20内へ送り込まれ、そして配分器側管転轍器24の反転の過程にモ ルヒ弁体56を介して高圧搬送導管20から出てくるようにするのが有利である 。基本的には、モルヒ弁体56を管転轍器24の前に設ける代りに貯槽18の範 囲に設けることが可能である。この場合は、分離体50は戻し導管45を介して ポンプ側に逆送される。 結局、次のように要約することができる。 本発明は、濃厚物質、特に液状コンクリートを遠くへ搬送するための装置に関 する。この装置は、入口側にて搬送すべき濃厚物質を供給可能な濃厚物質ポンプ 12と、高圧搬送導管20を介して濃厚物質ポンプ12の圧力接続管30に接続 可能であり、かつ特にトンネル型枠配分器として構成された濃厚物質配分器10 とを具備する。高圧搬送導管20は、ポンプ側および配分器側にて2つの接続部 26、32、40、44の間で交互に切り替え可能なそれぞれ1つの管転轍器2 2、24に接続されている。この場合、ポンプ側管転轍器22は、その1つの接 続部26にて濃厚物質ポンプ12の圧力接続管30と、そして他の接続部32に て貯槽18を介して低粘性圧力媒体を付与可能な圧力媒体ポンプ16の圧力接続 管36と結合されている。他方において、配分器側管転轍器24は、その1つの 接続部40にて濃厚物質配分器10と、そしてその他の接続部44にて戻し導管 45を介して圧力媒体ポンプ16の貯槽18と結合されている。配分器側への間 違った付与を防止するため、配分器側管転轍器24は、到達する搬送材料流に生 ずる材料交換に応じて切替え可能となっている。DETAILED DESCRIPTION OF THE INVENTION       Equipment for transporting concentrated substances   The present invention relates to a pressure pump for the concentrated substance pump, which is connected to the concentrated substance pump via a high-pressure conveying conduit.
